LAS 4 - Materials in Sewing and Fabric Preperation

• Fabric - is made from fibers that may either be natural or synthetic
• The 3 Types of fabrics are - Natural Fabrics, Silk and Wool and Synthetic Fibers (rayon, nylon and polyester)
• Natural Fabrics - come from plants, Examples are cotton and linen
• Silk and Wool - come from animals
• Synthetic fibers - are artifically produced with the use of chemicals, Examples are rayon, nylon and polyester
• Threads - come from fiber that may be natural or synthetic
• Threads are classified according to texture, number and letter and sold in different forms
• The higher the number, the finer the thread. Thread marked with letters stands for A-fine thread and D-thicker thread
• Fasteners - are devices used to easily close and open the openings or different garments.

  Examples are: zippers, buttons, snaps and hook and eyes
• Fabric Preperations: Soaking, Drying, Straightening and Pressing
• Soaking - fabrics and immersed in a basin of water before cutting to ensure that they will neither shrink nor fade
• Drying - Fabrics are hung and dried after soaking
• Straightening - the lengthwise and crosswise grain lines of the fabric are checked if the threads run parallel to eachother. If not, straighten the fabric by pulling and stretching until arment and selvaged are balanced
• Pressing - fabrics are ironed after straightening
• These are the fabrics to be prepared before sewing a garment: Fabric, Threads and Fasteners
